A passage 1'7, extending verticaliy at the upper extremity oi the casing 12 communicates with an eiongated passage 18 which extends horizontally and opens in the side wall of the oirc-uiar opening 7. The latter passage preferabiy provided with a needle valve 19 through the medium of which desired and justments may be obtained, and the solenoid is eonnected. with the battery circuit t rough the wire 20 and bindin post 21, the circuit being completed. throng grounding through the motor. I

The tubular extension 16 of the casing 11 is connected to the fuel line 22 by means of a sin-jut length of small copper tubing 23 and a- T-union E34.

In operation, when the electric or primery starter is energized, the motor is turned over. simultaneousiy 'a suction is 'produced in the throat of the carburetor, and this suction serves to rapidly rotate the mixing fan or eiement 9 carried in the circular L asket. Concurrently, the core 13, having t e valve 14 therewith, is caused, by the action of the solenoid, to recede from its seat 15, whereupon raw fuel drawn through the tubing 23, passages 17 and 18 and forcibly impinged against the blades 9 of the mixing element. An increment in the speed of the fan is immediately produced with the result that the raw fuel is thoroughly broken up before it passes through the intake into the motonf And while the fuel is thoroughly mixed at. this point, it should be understood that the resultant mixture is considerably richer than would ordinarily obtain in the absence of my attachment, in fact, the mixture is sulficientiyric-l'i to start the motor almost instontly, even though it may! be exceedingly cohl. The point to bear in mind in this connection is that, with the incorporation of my mmtwn W1 quid fuqai d emten 61% m mama,
